With continuous technological advancements, various models and specifications of PCB drill bits have emerged, each with significant dimensional differences. The production process of PCB drill bits first involves rough grinding and fine grinding of the bar stock to achieve the desired diameter.

[0003] In existing technologies, rough grinding and fine grinding are performed using different equipment. During the grinding process, the bar stock needs to be supported by a support bracket to complete the processing. However, when processing different types and specifications of bar stock, existing equipment requires adjusting the bracket position, which is a cumbersome process that requires repeated adjustments to achieve the correct alignment, resulting in low production efficiency and complex operation. Utility Model Content

[0010] More preferably, the synchronous follow-up support device of the bar grinding machine also includes an anti-slip pad, which is set on the support surface of the first support block and the second support block.

[0011] Compared with the prior art, the present invention has the following advantages: 1. By rotating the first frame rod, rotating the second frame rod and their rotating shafts, a multi-angle adjustment structure is formed, which solves the problem of adapting to the processing of bar stock of various specifications and improves the versatility of the device.

[0012] 2. By utilizing the automatic reset function of the tension spring, the number of steps and time for manual adjustment by operators is greatly reduced. This not only reduces the difficulty of operation but also improves the efficiency and consistency of adjustment, making the device more convenient and efficient when continuously processing bars of different specifications.

Detailed Implementation

[0019] A synchronous follower bracket device for a bar grinding machine, see [link / reference] Figures 1-4The system includes a mounting frame 1, a rotating frame rod 1 2, a rotating shaft 1 3, a material support block 1 4, a rotating shaft 2 5, a rotating frame 2 6, a wedge block 7, a material support block 2 8, a tension spring 1 9, a tension spring 2 10, a rotating wheel 11, a limiting component, and an anti-slip pad. The rotating shaft 1 3 is located at the right end of the mounting frame 1. The rotating frame rod 1 2 is rotatably connected to the mounting frame 1 via the rotating shaft 1 3. The rotating shaft 2 5 is located at the lower end of the rotating frame rod 1 2. The rotating frame 2 6 is rotatably connected to the rotating frame rod 1 2 via the rotating shaft 2 5. The rotating frame rod 1 2 and the rotating frame 2 6 form a multi-angle adjustment structure through the rotation of the rotating shaft 1 3 and the rotating shaft 2 5. The limiting component is located on the rotating frame 2 6 to restrict its rotation range. The material support block 1 4 is located on the rotating frame rod 1 2, the material support block 2 8 is located on the rotating frame 2 6, and the anti-slip pad is located on the material support block 1 4 and the material support block 2 8. On the support surface of material block 2 8, anti-slip pads are used to increase the friction between material support block 1 4 and material support block 2 8 and the PCB drill bit rod. Material support block 1 4 and material support block 2 8 work together to support the PCB drill bit rod, ensuring positioning and stability during processing. Wedge block 7 is set at the lower end of mounting frame 1, and rotating wheel 11 is set at the bottom left end of rotating frame 2 6. Wedge block 7 is used to adjust the overall support angle of material support block 1 4 and material support block 2 8. Rotating wheel 11 and wedge block 7 work together to assist the movement and positioning of the rod, improving the flexibility during processing. Tension spring 1 9 is connected between rotating frame 2 6 and rotating frame rod 1 2, and tension spring 2 10 is connected between mounting frame 1 and rotating frame rod 1 2. The elasticity of tension spring 1 9 and tension spring 2 10 respectively realizes the automatic reset and adjustment of material support block 1 4 and material support block 2 8.

[0020] In use, the PCB drill bit is first placed between support block 4 and support block 8. Support blocks 4 and 8 together support the bit. The anti-slip pads on support blocks 4 and 8 increase the friction with the bit, preventing it from slipping during processing. Rotating frame rod 2 is movably connected to mounting frame 1 via rotating shaft 3, and rotating frame 6 is movably connected to rotating frame rod 2 via rotating shaft 5. Together, they form a multi-angle adjustment structure.

[0021] According to the specifications of the bar stock, adjust the angles of rotating frame rod 1 (2) and rotating frame 2 (6) to ensure that support blocks 1 (4) and 2 (8) are in the appropriate positions to accommodate the processing requirements of bar stock of different specifications. Wedge block 7 is located at the lower end of mounting frame 1. Its wedge structure adjusts the overall support angle of support blocks 1 (4) and 2 (8), ensuring stable support and processing accuracy of the bar stock. Tension springs 1 (9) and 2 (10) automatically reset support blocks 1 (4) and 2 (8) after adjustment, maintaining their support state and reducing the tedious steps of manual adjustment. Limiting components are located on rotating frame 2 (6) to restrict its rotation range, preventing over-adjustment and ensuring the safety and stability of the device. After the bar stock is positioned, start the processing equipment. Rotating wheel 11 cooperates with wedge block 7 to assist the bar stock in smooth movement between support blocks 1 (4) and 2 (8). The processing equipment performs rough and fine grinding on the outer diameter of the bar stock to achieve the predetermined diameter. During the processing, the device ensures stable support and smooth movement of the bar stock through multi-angle adjustment structure and the coordination of various components, and finally completes the efficient grinding processing of PCB drill bit bar stock.
